BACKGROUND OF THE INVENTION

1. The Field of the Invention

The present invention is directed generally to a multi-compartment bottle. More specifically, the present invention is directed to a multi-compartment drink bottle having a generally cylindrical and featureless inner wall and surfaces over which drinks or foods are received from the bottle.

2. Background Art

Multi-compartment bottles have been in existence for many years. However, the versatility of such bottles comes into question in daily use due to the following reasons. None of the existing multi-compartment bottles are capable of being accessed for cleaning in ways that are convenient to their users. Conventional multi-compartment bottles are typically characterized by containers which are not easily accessible using cleaning brushes and co-located access points. Often times, the openings of such containers are relatively small compared to the volume the containers hold or a cross-sectional area of the containers. Constant or frequent use of bottles can lead to the repetitive need for cleaning. If conventional bottles are left with standing fluid or water within them, mold, mildew, or bacteria develops and can lead to difficult cleaning and, possibly, health-related problems for the user. Conventional bottles have at least one single top or cap that is often removable by unscrewing or exerting upward pressure to separate the top or cap from the body of the bottle. However, due to the design and shape of conventional bottles, comprehensive cleaning is difficult. Multi-compartment bottles having juxtaposed containers and opposingly disposed access points present challenges in daily use because it is unintuitive the means by which the contents are accessed or the means by which, upon removal, the various parts of the multi-compartment bottles should be placed in a condition to avoid contamination. Multi-compartment bottles are typically used to hold different substances that are not to be mixed but are advantageous if carried together such that they may be used at the same location.

U.S. Pat. No. 4,444,324 to Grenell (hereinafter Grenell) discloses two embodiments of a compartmented storage container for liquids and foods. The containers have two identical juxtaposed cylindrical body members with insulated walls, open base ends and dispensing openings closed by a removable insulated closure. The open base ends are interconnected by a medial connector with an insulated annular flange. The medial connector can either be open or closed depending on whether the container is used to store one or two different liquids or foods. The medial connector includes externally disposed threads or external threads (39 of Grenell) which can easily come in contact with contaminants if the bottom compartment were to be opened by removing the medial connector. The number of compartments of Grenell cannot be extended beyond two compartments as a medial connector is unsuitable for being coupled with the internal threads of a cup end such that the medial connector can still be enclosed within a cup (22 of Grenell). During use, the internal threads (39 of Grenell) come in contact with liquids or foods held within the compartment. When a cup (22 of Grenell) is replaced, the liquids or foods caught on the internal threads tend to be ground and trapped between the external threads (38 of Grenell) and the external threads (39 of Grenell). Such trapping of materials makes cleaning of the cavity of the body member (24 of Grenell) difficult and causes unhygienic openings of the body member via which a drink or food is retrieved. BORN water bottles of http://techcracks.com/2012/03/born-water-bottle-concept-by-michael-lovett/ also show a medial connector having external engaging parts configured to be mated with an inner wall surface of a body member.

U.S. Pat. No. 5,499,738 to Burleigh (hereinafter Burleigh) discloses a container, for holding consumable substances, having a plurality of closures adapted to restrain the contained substances and dividing walls to divide the container into a plurality of substance-holding compartments, each compartment being associated with one closure respectively. Burleigh's container possesses dividing walls integrally constructed with the container and therefore not removable for cleaning. As each opening is substantially smaller in diameter than the diameter of the container and the container is not capable of being dismantled, cleaning of Burleigh's container presents a bigger challenge than cleaning of the present bottle.

U.S. Pat. Pub. No. 2012/0055935 discloses a cylindrical vessel comprising a dividing wall extending transversely across the cylindrical vessel separating the vessel into two portions, wherein the wall has sealable apertures therethrough. This disclosure shows a divider having selectively enabled apertures which allow communication between liquids held in the two portions. The other major difference between this and the present disclosure is the openable lid which is not reclosable.

U.S. Pat. Pub. No. 2006/0138169 discloses a multiple chamber container that has a first chamber and a second chamber separated by a divider positioned within an outer surrounding wall. An opening for the first chamber is provided on one end of the container, and an opening for the second chamber is provided on an opposite end of the container. The openings can each be selectively closed, such as with a removable cap. This disclosure shows an “internal divider” that is integrally built with two compartments. The compartments also come in irregular shapes which are more challenging to clean than the compartments of the present container.

Thus, there arises a need for a multi-compartment drink bottle having easy-to-clean surfaces which come in contact with the drinks or foods that are held within and being dispensed from the bottle. There also arises a need for a multi-compartment drink bottle which is intuitive, easy and hygenic to use.

PARTICULAR ADVANTAGES OF THE INVENTION

The present multi-compartment drink bottle provides compartments that are sanitary and easy to clean. Mating surfaces are advantageously disposed to avoid being soiled or such that contaminants are not ground into mating surfaces, causing the surfaces to be difficult to clean. No part of the drinks and foods supplied in the bottle comes in contact with contaminants in storage or during consumption. The present bottle may be configured to yield more than two compartments as desired by a user. The contents of each compartment of the present bottle can be accessed in more than one way. The present bottle is versatile in that it is capable of receiving various types of unions equipped with, e.g., filter, thermally conductive material, thermally insulative material, etc.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

The term “about” is used herein to mean approximately, roughly, around, or in the region of. When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 20 percent up or down (higher or lower).

FIGS. 1 and 2 are top perspective and front orthogonal views, respectively, of a multi-compartment drink bottle 2 according to the present invention. The bottle 2 comprises at least two nipples 4, at least two end caps 8 and at least one union 6. Each nipple 4 is essentially a substantially cylindrical hollow tube having two opposingly disposed ends, a diameter and an external mating surface disposed on each of the two opposingly disposed ends of the hollow tube.

In a preferred embodiment, the nipples 4, end caps 8 and union 6 are constructed from stainless steel which does not leach harmful chemicals into drinks or foods contained in the bottle. The Applicant discovered that certain polymeric materials including High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Polypropylene (PP), Copolyester or Polyethylene Terephthalate.are also suitable for use in constructing such parts. In yet another embodiment, the nipples, end caps and union may be constructed from a variety of materials disclosed elsewhere herein. For instance, the nipples may be constructed from stainless steel for strength while the end caps may be constructed from a polymeric material to dampen negative acoustic effects of stainless steel while the bottle is in use. A stainless steel component may alternatively be coated with a polymer to achieve similar acoustic effects.

FIG. 3 is an exploded view of a multi-compartment drink bottle according to the present invention. Two compartments may be formed from the hardware pieces shown. Each compartment may be formed by mating a first end of a nipple 4 with a first end cap 8 and mating a second end of the nipple 4 with a second end cap 8 or a first end of a union 6. In order to build two juxtaposed compartments, a second nipple 4 is mated at a first end with a second end of the union 6 and an end cap 8 at a second end of the second nipple 4.

It shall be apparent that, in order to build an additional compartment, a second union 6 may be mated with the second end of the second nipple 4 such that another nipple 4 may be mated with the second union 6. A ledge 32 is preferably disposed around each end of a nipple 4 such that a seal 18 such as a rubber gasket or O-ring may be disposed between an end cap 8 and a nipple 4 or a union 6 and a nipple 4 as the seal 18 is compressed to further aid in sealing the compartment formed as a result of engaging a nipple with an end cap 8 and/or a union 6.

Referring back to FIG. 3, the internal mating surface 12 comprises screw threads and the external mating surface 10 comprises screw threads configured to mate with the screw threads of the internal mating surface 12. It shall be noted that by disposing a mating surface externally on each end of the nipple 4, a cylindrical but otherwise featureless compartment is formed for holding drinks or foods. The interior surfaces of such a compartment is easily cleaned or sanitized as they are constructed from smooth surfaces which are void of screw threads, bumps, ridges, crevices, protrusions, etc. In order to consume a drink or food (contents) from a compartment, a user simply places his or her mouth on a portion of the rim of one end of a nipple 4. As such, the contents do not come in contact with (or flowing over) a mating surface as such a mating surface is disposed externally of the compartment. Conversely, if a mating surface had been disposed internally on each end of the nipple 4 (such as in the case of Grenell), such mating surface would come in contact with the contents of the compartment.

Repeated engagement and disengagement of the internal 12 and external 10 mating surfaces can cause food and drink matter to be ground into the mating surfaces and present significant challenges to clean. In another embodiment not shown, the internal mating surface 12 comprises quick snaps while the external mating surface 10 comprises quick snaps configured to mate with the quick snaps of the internal mating surface. Each end cap 8 includes an internal mating surface configured to be mated with one end of a nipple 4. The outer surface 32 of an end cap 8 is preferably perpendicularly disposed with respect to the central axis 30 of the bottle. Gripping aids 16 such as bumps, ridges, depressions and non-slip surfaces may be disposed about the outer surfaces of end caps and unions to facilitate hand grips when assembling or dismantling the compartments. Although not depicted, such gripping aids may also be disposed on portions of the outer surfaces of the nipples 4 to enhance gripping further. FIG. 4 is a front orthogonal cross-sectional view as taken along line A-A of FIG. 1. Each union 6 includes a substantially cylindrical hollow tube having two opposingly disposed ends, a diameter and a dividing wall 14 disposed within the hollow tube of the union 6, isolating material connection between the two opposingly disposed ends of the union. In a preferred embodiment, the diameter of the hollow tube of a union is substantially the same as the diameter of the hollow tube of each nipple to facilitate the interchangeability of an end cap and one end of a union. In one example, the two compartments may be filled with two different types of drinks.

Certain markings 36 (see FIG. 3) may be integrally formed into nipples 4 or end caps 8 such that the top and bottom compartments may be differentiated to avoid mix-up of compartments during use. FIG. 5 is a front orthogonal cross-sectional view according to the present invention, depicting another embodiment of a union. In this embodiment, the dividing wall of FIG. 4 is replaced with a perforation 34, thereby allowing communication between the top and bottom compartments. Such a union is useful when the drinks or foods held in the compartments are not to be segregated. In this embodiment, the compartments are combined to make a cavity about twice as large as a single compartment.

FIG. 6 is a front orthogonal cross-sectional view according to the present invention, depicting yet another embodiment of a union. In this embodiment, the dividing wall includes at least one protrusion 44 for increasing the surface area of the dividing wall via which heat transfer occurs. In this example, one of the compartments is filled with ice cubes while the other is filled with a drink 46 intended to be chilled using the ice cubes 48 in the adjacent compartment. As drink 46 contacts the protrusion 44, heat is transferred by conduction through the protrusion 44 to the ice cubes 48. The protrusion 44 increases the surface area via which heat transfer can occur. The dividing wall may alternatively be configured to include one or more protrusions extending in the direction opposite of the protrusion 44 presently shown in FIG. 4B from the dividing wall. With this alternative configuration, heat can be more readily transferred from the compartment containing drink 46 to the compartment containing ice cubes 48, thereby chilling the drink 46. In a preferred embodiment, the ratio of the length 50 of the protrusion 44 to the height 52 of the compartment into which the protrusion 44 reaches ranges from about 1/20 to about 19/20. If there are multiple protrusions extending from a face of a dividing wall, these protrusions are preferably dispersed with sufficient space between protrusions to allow use of commonly available cleaning brushes and to eliminate difficult-to-clean surfaces. In this embodiment, the dividing wall is preferably constructed from an excellent thermal conductor, e.g., stainless steel, etc.

FIG. 7 is a front orthogonal cross-sectional view according to the present invention, depicting another embodiment of a union. In this embodiment, the dividing wall 14 comprises an air gap 20 configured to thermally isolate the top and bottom compartments in order to reduce thermal communication between the contents of the top and bottom compartments. The provision of an air gap 20 is especially useful if there is a need for thermal isolation and that the dividing wall is constructed from an excellent thermally conductive material, e.g., stainless steel.

FIG. 8 is a front orthogonal cross-sectional view according to the present invention, depicting yet another embodiment of a union. In this embodiment, the dividing wall 14 shown in FIG. 4 is replaced with a filter 22. In use, one can simply open the top end cap 8 and scoop feed 24 from a creek or pond, etc., and leave the top end cap 8 off and let the feed filter to the bottom compartment. In order to access the filtrate 26, the union 6 can then be removed or the bottle may be turned upside down such that the bottom end cap 8 will now be disposed on the top and be removed.

FIG. 9 is a front orthogonal cross-sectional view according to the present invention with the bottle disposed on a supporting surface and the end cap 8 of the top compartment removed such that the contents of the top compartment can be accessed. It shall be noted that the bottle can be disposed on a supporting surface 28, in an upright position, without exposing any contents contacting portions of the bottle with the supporting surface 28. In one embodiment, the height 40 and diameter 42 of a compartment measures about 4.5 inches and about 2.5 inches, respectively.

FIG. 10 is a front orthogonal cross-sectional view according to the present invention with the end cap of the top compartment removed and the bottom compartment removed from the union such that the contents of the top and bottom compartments can be accessed. Again, none of the contents contacting portions of the bottle are exposed to the supporting surface 28. In contrast, upon detachment from the bottom compartment, the exposed mating threads (39 of Grenell) of the medial connector can come in contact with a supporting surface on which the Grenell's top compartment is disposed unless the top compartment is flipped over such that Grenell's top cup comes in contact with a supporting surface. Grenell's mating threads also do not provide a stable base for setting the top compartment in the upright position securely as their diameter are substantially smaller than the diameter of a body member (24 of Grenell). In contrast, a present union lacks protrusions, i.e., external mating surfaces jutting out from the two opposingly disposed ends of the connector flange (36 of Grenell). If Grenell's bottom compartment is to be accessed by removing the connector flange (36 of Grenell), the top compartment (with the connector flange still attached to the top compartment) must be flipped over such that the cup of the top compartment can be seated on a supporting surface.

FIG. 11 is a top perspective view of a multi-compartment drink bottle according to the present invention, depicting the roll-off of condensate 38 from vertical surfaces of the bottle 2. As the vertical surfaces of the bottle are smooth and substantially parallel to the vertically disposed central axis 30, any condensate 38 that forms on the vertical surfaces tends to roll off from the surfaces without collecting in any crevices. As such, a user taking a drink from the bottle by tilting the bottle will not experience excessive drips of condensate back on the user.
